Slasher, you have had a month in which it could have sorted itself out. That is more than enough time. Stop messing about and get to the doctor. Forget all the nonsensical claptrap about re-colonising your bowel, the only time it might make any sense is after a course of antibiotics. Research has shown that all this drink-a-tub-of-yoghurt-a-day malarky is just that. You have been eating your normal diet of many years standing and something has changed with the inner workings and THAT needs proper attention. So, until all is proved to be normal you have to regard it as abnormal and no matter how embarrassing the subject you need to get to your doctor. Stop procrastinating.
A little tale from a Consultant Surgeon (now retired) giving us a lecture on problems of the urinary tract. "What", he said, "would you rather have, painful or painless mictirition?" He opted for painful as it had less association with malignancies. That is NOT to say that painless problems mean something is malignant.
